BACKGROUND: Lower urinary tract symptoms significantly worsen quality of life. The hypothesis that they might lead to serious systolic blood pressure alterations through inducing sympathetic nervous activity has not been studied so far. OBJECTIVES: To investigate the relationship between benign prostate enlargement-related storage and voiding symptoms and systolic blood pressure. DESIGN AND SETTING: Cross-sectional single-center study on data from a hospital patient record system. METHODS: We evaluated the medical records of all consecutive patients with benign prostate enlarge-ment-related lower urinary tract symptoms admitted between January 2012 and December 2017. Storage and voiding symptoms were assessed separately. International Prostate Symptom Score, uroflow-metry, postvoiding residual urine volume and systolic blood pressure were recorded. Pearson correlation and linear regression analysis were used. RESULTS: Positive correlations were found between systolic blood pressure and all of the storage symp-toms. Among these, urgency had the most significant effect. There were 166 patients (41.4%) with urgency for urination, which increased mean systolic blood pressure from 124.88 mmHg (average value in elevat-ed blood pressure group) to 132.28 mmHg (average value in stage-1 hypertension group). Hesitancy in urinating and feeling of incomplete bladder emptying had weak positive correlations with systolic blood pressure. There was a negative correlation between systolic blood pressure and intermittency of urination. CONCLUSIONS: With increasing numbers of urine storage symptoms, systolic blood pressure also in-creases, while the opposite occurs for voiding symptoms in patients with benign prostate enlargement. We conjecture that storage symptoms may lead to this increase through inducing sympathetic hyperac-tivity. Further prospective studies with larger groups are needed to confirm these findings.
